摘　　要：基于中国道路交通事故深入研究(CIDAS)数据和人体模型THUMS的事故仿真,研究了行人与普通轿车、SUV和MPV 3种典型车型碰撞过程中,头部与车体的碰撞状况和响应特点。结果表明,行人头部与车辆的碰撞位置、碰撞角度、碰撞速度和损伤程度均与碰撞车辆类型有密切关系。普通轿车与行人头部碰撞点位置的WAD值比其他两种车型大。行人头部与普通轿车的碰撞角度比另两种车型大,而相对碰撞速度则比另两种车型低。该研究结果可为新车行人保护设计与行人保护法规制定提供参考。The situation and response features of the impact between human head and vehicle body in the collision process between pedestrian and three typical vehicle models （ normal car, SUV and MPV） are studied based on the data of CIDAS （China In-depth Accident Study） and the accident simulations with human model THUMS. The results show that the position, relative angle and speed of impact and injury severity all closely related to vehicle model. The wrap around distance of the hitting point of human head against vehicle body of normal car is larger than that of SUV and MPV, the impact angle between human head and vehicle body of normal car is also larger than that of SUV and MPV, while the relative impact speed between human head and vehicle body of normal car is lower than that of SUV and MPV. The outcomes of study provide references for the new vehicle design and regulation formulation in pedestrian protection.
